procesing error ; Error opening serial port /dev/cu.Angelmansiphone-Wireles-1:p

In my processing project I get the error;

Error opening serial port /dev/cu.Angelmansiphone-Wireles-1:port busy.

Except that in arduino I am using the usb modem port 1421

For some reason the Processing is looking in the wrong port for the arduino program,

Any ideas?

I'm not a processing user, but I guess processing is looking at the port that is specified in the code.
